The location of the apartment is great, walkable to the BTS and many restaurants, malls etc. It's perfect for a short stay in Bangkok. The room was small but clean and comfortable and the use of a washing machine was helpful for us. Unfortunately we had no hot water for the first 2 days but Noon did offer a different building to shower in if we wanted.
The only downside was a lack of kitchen equipment (we had to buy mugs, bowls and cutlery as there was a mix match of left over things there) and also the room is very dark with very little natural light coming in as the windows face a brick wall. Noon was very good with communication and the check in instructions were easy to follow. One slight problem for us was not being able to get a TM30 (we needed this for immigration) so we had to move to another place after our 1 week stay. This seems common for condos in Thailand though as I don't think they are supposed to be rented for short term stays!
